Background and context:
1. Instagram by default requires you to be logged in.
2. Your account can LIKE posts.
3. Getting all of your likes from IG can be a pain.
As an active IG user, I want to be able to download only posts I've liked.
The information of whether or not your logged-in user has liked the target post is available in the API results, but was not available to the end-user for filtering.
This small change allows `user_has_liked` to be used to e.g. download only liked posts of an entire IG account.
Example use:
```
$ gallery-dl --cookies-from-browser FIREFOX--filter 'user_has_liked' https://www.instagram.com/imgur/
```
This will only download the posts that have `has_liked: True` set in the returned REST API data.
Note: it will still need to loop through the entire account's posts since this is done per-post basis instead of looping just the liked posts, but at least you are able to use this IG feature as a download marker.
currently causing errors in the setup phase:
Error: Could not find a version that satisfies the requirement pip
Error: No matching distribution found for pip
Error: The process '/usr/bin/bash' failed with exit code 1
e.g. when 'browser' is set to a non-empty value and gallery-dl creates
its own SSLContext instance instead of using requests' and urllib3's
defaults.
urllib3 disables this option for its default contexts,
since it does this check on its own.
Fixes "ValueError: Cannot set verify_mode to CERT_NONE when
check_hostname is enabled" when using --no-check-certificate.

When reading cookies from the browser, the user is able to give either just the browser name, or also provide profile/container information.
If an exact profile is provided, there is no need to find the latest profile with `os.walk` which is very expensive.
This change optimizes that case and the performance increase is significant (~8 sec to 0.6 sec).

this disables the ability to directly apply […] to '…' literals,
but that's not really useful anyway and can still be done with _lit
